PIPE CUTTING AND GROOVING MACHINE.

Application filed October 4, 1924. 7 Serial No. 741,677.

To all whom it may concern: v

Be it known that I, HENRY W. ROTH, a

citizen of the United States, residing at Tuscarawas, in the county of Tuscarawas and State of Ohio, have invented new and useful Improvements in Pipe Cutting and Grooving Machines, of which the following" is a specification.

My invention is a pipe cuttlng and grooving or corrugating machine and its primary object is to provide a mechanism which will simultaneously sever the .pipe into the proper lengths and at the same time groove the periphery thereof. i

A further object of the invention is to provide a machine for seve'ring sewer pipes into desired lengths and corrugatingthe ends thereof in a single operation and'which will facilitate the work as well as, the saving of manual labor.

The invention alsocontemplates a mechanism supported to rotate about an axis and equipped with adjustable cutters or groove formers which are so arranged as to regulate the cuts or depths of the groove.

\Vith the preceding and other objects and advantages in mind the invention consists in the novel combination of elements, construction and arrangement of parts and operation to be hereinafter specifically referred to, claimed and illustrated in'the accompany ing drawings in which: i

Figure 1 is a side elevation of ap'ipe cutting and grooving machine constructed in accordance with the present invention and showing the machine in operation;

F igure 2 is an enlarged view of the machine, partly in vertical section and partly in elevation;

Figure 3 is avertical sectional view taken on the line 33 of Figure 2;

Figure 1 is detail horizontal sectional view of parts of the invention;

Figure 5 is a similar view taken on the line 5-5 of Figure 2; and

Figure 6 is transverse sectional view taken on the line 66 of Figure 2.

Referring to the drawings in detail wherein corresponding parts of the reference denote corresponding parts of the several views, the numeral 5 designates a vertically arranged rod adapted to be supported from a ceiling or other structure not shown. Rotatable about this rod 5 is a sleeve 6 of a relatively great thickness having a bore end resting upon a collar 7 formed on this rod 5.

the inner end of its horizontal arm fixed to the sleeve 6 by means of a threaded con- I nection 9.

A casing 10 is associated with the lower end of the vertical arm of the bracket 8 and is provided with attaching means for this purpose indicated at 11. Horizontally movable through a transverse opening inthe lowerend of this vertical arm is a rack bar 13 carrying a-rectangular head 14 upon its inner end, the latter being; provided with a plurality of spaced horizontal slots 15 each of which rotatably receives a grooving roller 16. A pin 17 extends through this head ,and thru the grooving rollers 16. Journaled in the casing 10 to rotate about ahorizontalaxis is a relatively large pinion 18meshing with the rack bar 18.

Depending fromgthe horizontal arm of the bracket 8, at a point intermediate its end and constructed from piping or tubing is a substantially elliptical shaped guide 19including parallel guide members 20, extend ing between these guide members 20 and through a slot/21 in the vertical leg of,the bracket 8 is an angularly "disposed lever 22 which is pivoted tothis bracket as indicated at 23. A vertically movable reciprocable bar designated at'24 has its upper end pivotally connected" with the upper end of the lever 22 and its lower end is formed with rack teeth 25 meshing with a small pinion 26 fixed to the pinion 18. A flanged collar 27 is vertically adjustable upon the lower end of the rod 5 and is maintained in adjusted positionby means of a set screw 28. As shown in Figure 6 the lower end of the lever 22 is forked or. bifurcated and is engaged with a flanged collar 27.

It is also apparent that upon adjustment of the collar 27 the lever 22 will be rocked about its pivot impartng longitudinal move ment to the bar 2 1 and through the instrumentality of the pinions and the rack bar 13, the grooving element 16 will be carried into engagement with the periphery of a length of pipe designated at P so that the same will be provided with peripheral grooves of a desired depth.

In order to sever the pipe into equal lengths a horizontally disposed cutter wire 29 has one end connected with an eye 30 carried by the vertical leg 8 while its opposite The sleeve being adapted to rotate about the rod 5. An L-shaped bracket constructed of piping and designated at 8 has passes through a stem 31 depending from the guide 19 and has an adjusting nut threaded therein.

Vhile I have shown and described the preferred embodiment of the invention it is to be understood that I reserve the right to make changes in the arrangement of parts, construction and form as will not depart from the spirit of the invention or the scope of the appended claims.

Having thus described the invention, I claim:

1. A device of the character described, comprising a rotatably mounted bracket, a casing carried by the. lower end thereof, gearings in the casing and a plurality of rollers rotatable about the single axis and adapted to groove the periphery of a pipe, the rollers being adjusted horizontally by means of the operation of the gearings. and manually operable means operating the gea rings to adjust the rollers to the work.

2. A device of the character described comprising bracket rotatably mounted, a casing carried by the lower end thereof, gearings in the casing and a plurality of rollers rotatable about a single axis and adapted to groove the periphery of a pipe, the rollers being adjusted horizontally by means of gearings, and manually operable means operating the gearings to adjust the rollers to the work, and a pipe severing element associated with the bracket at a point slightly above the rollers.

3. A space bar pipe grooving and severing device comprising vertically arranged stationary rod, a sleeve revoluble about the rod, a bracket carried by the sleeve, rollers associated with the bracket and capable of horizontal adjustment toward the work, and a cutting element associated with the bracket.

4. A pipe cutting and grooving device comprising a vertically arranged stationary rod, a bracket rotatably associated with the rod, a rack bar associated with the bracket, series of grooving rollers carried by the inner end of the rack bar, a pinion meshing with the rack bar, a lever pivoted to the bracket, operative connection between the lever and pinion for rotating the latter and means on the rod for rocking the lever and retaining the same in rocked position whereby to hold the grooving rollers in adjusted position through the medium of the pinion.

5. A pipe cutting and grooving device comprising a vertically arranged stationary rod, a bracket rotatably associated with the rod, a rack bar associated with the bracket, series of grooving rollers carried by the inner end thereof, a pinion meshing with the rack bar, a lever pivoted to the bracket, operative connection between the lever and pinion for rotating the latter means on the rod for rocking the lever and retaining the same in rocked position whereby to hold the grooving rollers in adjusted position through the medium of the pinion, a guide depending from the bracket, a stem depending from the guide and a cutter wire stretched between the stem and bracket.

6. A pipe grooving device comprising a vertically arranged stationary rod, a bracket rotatably associated with the rod, a rack bar associated with the bracket, a series of grooving rollers carried by the inner end thereof, a pinion meshing with the rack bar, a lever pivoted to the bracket, an operative connection between the lever and pinion, and means on the rod for rocking the lever and retaining the same in rocked position whereby to hold the grooving rollers in adjustment.

In testimony whereof I aflix my signature HENRY w. ROTH.
